How to Convert 3D Model Files Online
Convert 3D files in the browser without installing Blender or any desktop app. Use GLB/GLTF for websites and Unity/Unreal, STL or 3MF for 3D printing, USDZ for Apple AR, OBJ for DCC tools like Blender and Maya.
- Upload your file — drag and drop or choose a model up to 50MB. Supported: OBJ, STL, GLB, GLTF, USDZ, DXF, PLY, 3MF, or ZIP.
- Select output format — GLB for web/engines, STL for 3D printing slicers, USDZ for iPhone AR, OBJ for Blender/Maya, PLY for scanning workflows.
- Convert and download — then open GLB/GLTF in the 3D File Viewer to verify before importing.
Common conversion guide:
| Use case | Example | Input | Output |
